MFD Mechanical Fireplace Damper

A chimney top mounted automated damper for use with gas fireplaces and model RS Chimney Fan. The MFD prevents excess heat from escaping through the chimney when the fireplace is not in use. The ultra low profile MFD comes equipped with an actuator that is interlocked to the ADC 100 so it only opens when the fireplace is in use and draft is proven.
